少不了踩坑。尤其是在做文章内对tag自动增加删减功能时候。文章编辑页内增加tag ，如果该tag存在，则更新计数，不存在则加；文章内删减tag，就需要自动对tag进行更新计数。因为tag与文章是一对多的关系 。而且一次可能要加多个或者删减多个，这就需要循环删除。而且判断也先需要查询。但是mongose所有的增删改查都是异步，导致后面判断先执行 ，最后并没有结果输出，解决办法就是使用promise.all()方法循环，不知道怎么回事mongoose增删改查返回的不是promise对象，每次都要转下麻烦。</p></li><li><p>权限检查以及登录状态检查产生大量重复代码，未做封装复用。将其单独抽离出来后，请求报错....</p><p>&nbsp;</p></li></ul></div>
